It can fix or shift gears to change the transmission ratio between the output shaft and the input shaft. The transmission consists of a speed-changing transmission mechanism and a control mechanism. Some vehicles also have a power take-off mechanism. Most transmission mechanisms use ordinary gear transmissions, and some use planetary gear transmissions. The ordinary gear transmission speed-changing mechanism generally uses sliding gears and synchronizers, etc.

[0003] After the production of an automatic vehicle transmission is completed, a series of comprehensive inspections are required. Among them, the engine oil in the gearbox needs to be extracted, and then automatic flaw detection is carried out on the local inner wall. After the corresponding inspection is completed, the engine oil is introduced again. The process of oil inlet and outlet is generally manually carried out by workers, which is not only troublesome and affects efficiency, but also increases labor costs. Content of the Utility Model

Specific embodiments

[0019] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0020] Secondly, the present utility model will be described in detail in combination with the schematic diagrams. When describing the embodiments of the present utility model in detail, for the convenience of description, the cross-sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples, which should not limit the scope of protection of the present utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0021] In order to make the purpose, technical solutions, and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Figures 1 - 3 Shown is a schematic diagram of the entire structure of an automatic vehicle detection device of the present utility model. Please refer to Figures 1 - 3 , an automatic vehicle detection device of this embodiment includes a base 100. Positioning fixtures 200 are respectively arranged at the front and rear ends of the upper part of the base 100. A gantry 300 is self-driven and slidably arranged along the length direction of the upper end and both sides of the base 100. The inner top of the straight section of the gantry 300 has a chute 320 arranged along the width direction of the base 100. A slider 400 is slidably matched inside the chute 320. The gantry 300 also has a reciprocating drive assembly 500 that can drive the slider 400 to move back and forth along the direction of the chute 320. A lifting assembly 600 is arranged at the bottom of the slider 400. A fuel storage tank 700 is arranged at the output end of the bottom of the lifting assembly 600. An oil suction needle tube 710 is arranged at the bottom of the fuel storage tank 700. A pneumatic control joint 730 connected to an air pump is arranged on one side of the upper part of the fuel storage tank 700; among them, this automatic vehicle detection device is also equipped with a general control center, that is, a controller.

[0023] At the front and rear ends of the upper part of the base 100, there are respectively two working stations 110 and 120 for the positioning fixtures 200 to match, and the sizes of the working stations 110 and 120 are the same. By arranging the working stations 110 and 120 at the front and rear ends, two positioning fixtures 200 can be arranged simultaneously. The positioning fixtures 200 are used to position and stabilize the transmission. The positioning fixtures 200 can also be equipped with pneumatic clamps, etc., which are set according to actual needs. During specific use, when the transmission in one side of the positioning fixture 200 is being detected, the feeding robotic arm or the staff can place the transmission on the other side into the positioning fixture 200 on the other side, and under the cooperation of the gantry 300 and the oil pumping mechanism, pump the oil from the transmission on the other side. After the detection is completed, the detected transmission on the other side after pumping the oil is then detected. In this process, by analogy, the previously detected transmission can be removed and a new transmission can be placed, and then rapid oil pumping can be carried out. In this way, the time consumption of mid - process shutdown is effectively reduced, and the detection efficiency of the device is improved.

[0024] It can be understood that the base 100 can install and position the positioning fixtures 200 for different models of transmissions through the working stations 110 and 120, improving the application range of the device.

[0025] On both sides of the upper end of the base 100 along its length direction, there are tracks 130. At the bottom of the two vertical sections of the gantry 300, there are electric sliding seats 310 that match the tracks 130. It can be understood that the gantry 300 can move automatically under the cooperation of the electric sliding seats 310 and the tracks 130. The staff can preset or control the electric sliding seats 310 through the controller, improving the automation level and detection efficiency of the device.

[0026] The reciprocating driving assembly 500 includes a lead screw 510 rotatably installed at both ends inside the chute 320 and thread - connected to the slider 400 through a ball - type nut, and a servo motor 520 arranged outside the gantry 300 with its output shaft connected to one end of the lead screw 510. Here, because the oil port positions of different transmissions are different, before pumping the oil, the gantry 300 will first move the oil storage tank 700 above the transmission, and then the servo motor 520 drives the lead screw 510 to rotate. Under the cooperation of the chute 320 and the nut, the slider 400 moves left and right until the oil storage tank 700 and the oil suction needle tube 710 at the bottom are vertically corresponding to the transmission oil port.

[0027] Furthermore, the lifting assembly 600 in this embodiment can be an electric push rod, a cylinder, a hydraulic rod, or a telescopic motor, etc. This embodiment is not limited to this.

[0028] The air pressure control joint 730 includes an air pipe 731 with one end communicating with the inner cavity of the oil storage tank 700 and the other end communicating with an air pump, and a solenoid valve 732 arranged on the air pipe 731; an electromagnetic flow valve 720 is also arranged at the connection between the oil suction needle tube 710 and the oil storage tank 700, and an air pressure sensor 750 is further arranged on one side of the top of the oil storage tank 700. In this embodiment, for example, when the oil suction needle tube 710 sucks or injects the transmission oil cavity, the electromagnetic flow valve 720 can detect the output and input amounts of the oil fluid in real time. When the set value is reached, the controller will automatically stop the air pressure control joint 730, the oil storage tank 700 and the oil suction needle tube 710 from continuing to suck or release, which is simple and practical; moreover, when the air pump sucks the air in the oil storage tank 700 through the air pipe 731, a negative pressure will be generated in the inner cavity of the oil storage tank 700, and the transmission oil cavity will be sucked through the oil suction needle tube 710. When the solenoid valve 732 is opened, the air pipe 731 will suck the free air at the air pump end under the negative pressure of the oil storage tank 700, so that the oil storage tank 700 will lose the negative pressure and input the oil fluid into the transmission through the oil suction needle tube 710 at the same time; in addition, the air pressure sensor 750 will monitor the air pressure in the oil storage tank 700 in real time to avoid excessive negative pressure in the box due to excessive suction.

[0029] Furthermore, a camera 740 is also arranged on one side of the bottom of the oil storage tank 700. It can be understood that during the process of the gantry 300, the reciprocating drive assembly 500 and the lifting assembly 600 driving the oil storage tank 700 and the oil suction needle tube 710 to move, the controller can accurately find the position of the transmission oil port through the camera 740 and control the operation of each drive unit, ensuring the operation accuracy.

[0030] Although the present utility model has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present utility model can be combined with each other in any way. The exhaustive description of these combinations is omitted in this specification only for the sake of saving space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
